Stems cell on contact lenses restore sight

These days there are so many advances using stem cells that it is hard to choose which one to talk about. Yet, here is an example that is worth sharing: harvesting stem cells from a patient's own damaged cornea, culturing them on a contact lens, and then placing the contact lens back on the patient's damaged cornea. Within 10 days the cells recolonize the cornea, leading to a significant sigh improvement within weeks.
